Photovoltaic Cell is an electronic device that captures solar energy and transforms it into electrical energy. It is made up of a semiconductor layer that has been carefully processed to transform sun energy into electrical energy. The term "photovoltaic" originates from the combination of two words: "photo," which comes from the Greek word "phos," meaning

Photovoltaic (PV) cells, or solar cells, are semiconductor devices that convert solar energy directly into DC electric energy. In the 1950s, PV cells were initially used for space applications to power satellites, but in the 1970s, they began also to be used for terrestrial applications.
A third type of photovoltaic technology is named after the elements that compose them. III-V solar cells are mainly constructed from elements in Group III—e.g., gallium and indium—and Group V—e.g., arsenic and antimony—of the periodic table. These solar cells are generally much more expensive to manufacture than other technologies.
A photovoltaic system is a set of elements that have the purpose of producing electricity from solar energy. It is a type of renewable energy that captures and processes solar radiation through PV panels. The different parts of a PV system vary slightly depending on whether they are grid-connected photovoltaic facilities or off-grid systems.
Solar cell researchers at NREL and elsewhere are also pursuing many new photovoltaic technologies—such as solar cells made from organic materials, quantum dots, and hybrid organic-inorganic materials (also known as perovskites). These next-generation technologies may offer lower costs, greater ease of manufacture, or other benefits.
Although silicon is the most used material, there are photovoltaic cells manufactured with other semiconductors, such as cadmium telluride. These alternative materials are usually applied in more specific solutions, like in light surfaces or of flexible design. Today, three types of photovoltaic cells are mainly used.
